Hi everyone,
I have read a few threads on this topic before and they are great but I have a slightly different question.
I have been given a task of using a ISD1820 to drive an outdoors speaker and I have a week to do it.
If I use it to drive a standard portable Bose speaker the audio quality is actually really good.
I got a small 8 ohm loudspeaker for use outdoors and the output from the ISD1820 board is not enough which was not unexpected.
So I built a amplifier (https://www.jaycar.com.au/the-champion-audio-amplifier-kit-with-pre-amplifier/p/KC5519) and tested it and it does a good job of amplifying the recording but it clips the signal and the voice is not recognisable.
As I am on a short timeline, has anyone used any "off the shelf" audio boards or kits which do a good job of removing noise, static etc?
If I had a few months I would play around with different chips and make a circuit that works great. As I only have a week I am a little pressed to find something that will work great.
I am in Australia.
I look forward to hearing your suggestions.
